Definitions

  • the present invention relates to a an electrical connector, and more particularly, to a protective cover for an electrical connector which electrically contacts a circuit carrier, and is configured in order to avoid damage from whisker formation.
  • circuit carriers for example, conventional printed circuit boards, are generally provided before the assembly thereof with printed conductor structures.
  • the printed conductor structures usually copper and the plated through holes, are provided with a protective layer.
  • the protective layer is to ensure that the soldering points which are to be formed during assembly satisfy electrical and mechanical requirements. These protective layers are thus used to ensure solderability and are often called solderable end surfaces.
  • the solderable end surfaces in current circuit carriers are generally formed from pure tin, because of the current demand for lead-free soldering.
  • tin surfaces tend, to a greater or lesser extent, to form so-called “whiskers” over the course of storage.
  • needle-shaped tin monocrystals may become a few micrometers in length and can severely impair the functioning of the circuit carrier.
  • the whiskers may, on the one hand, cause short-circuits through bridge formation but may also, on the other hand, cause considerable damage when broken off.
  • whisker formation cannot necessarily be explained, however, it is generally believed that mechanical stresses, due to stress-induced crystallization, may cause the whisker formation. In fact, it may take a seven week storage time at room temperature, for conventional tin surfaces to form whiskers with a length of 30 ⁇ m to more than 100 ⁇ m.
  • the whisker formation can be reduced.
  • whiskers either grow out of the contact regions in which they form, and may cause short-circuits, or else break off and may be present as undesired conductive contaminations.
  • a material displacement resembling the track of a snow plough results in an accumulation of tin in certain regions of the plated through hole.
  • the invention has been made in view of the above circumstances, and has an object, among others, of providing a protective cover for an electrical connector for contacting a circuit carrier.
  • the electrical connector for contacting a circuit carrier, includes an insulating housing, at least one contact assembled in the insulating housing, a contact portion positioned at one end of the contact for contacting a mating contact, a connecting portion at another end of the contact, a plated through hole of the circuit carrier connecting to the connection portion of the contact through an electrically conductive press-in connection, a protective cover, at least one opening in the protective cover through which the connecting portion of the at least one contact enters in an assembled state.
  • the protective cover is configured to cooperate with the contact and/or the electrically insulating housing in order to cover an intake region of the plated through hole toward the outside.
  • FIG. 1 shows a perspective view of an electrical connector for contacting a circuit carrier with a protective cover according to an embodiment of the present invention
  • FIG. 2 shows a perspective exploded view of detail 2 from FIG. 1 showing connecting portions assembled with the protective cover
  • FIG. 3 shows a perspective exploded view of detail 3 from FIG. 1 showing the connecting portions assembled with the protective cover;
  • FIG. 4 shows a schematic sectional view of the electrical connector with a protective cover in an assembled state according to another embodiment of the invention
  • FIG. 5 shows a schematic sectional view of the electrical connector with a protective cover in an assembled state according to another embodiment of the invention
  • FIG. 6 shows a schematic sectional view of the electrical connector with a protective cover in an assemble state according another embodiment of the invention
  • FIG. 7 shows a schematic sectional view of the protective cover according to the embodiment shown in FIG. 1 ;
  • FIG. 8 shows a schematic sectional view of the protective cover according to the embodiment shown in FIGS. 4 and 5 ;
  • FIG. 9 shows a schematic sectional view of a double layer protective cover
  • FIG. 10 shows a schematic sectional view of a single layer protective cover
  • FIG. 11 shows a schematic sectional view of the protective cover according to the embodiment shown in FIG. 6 ;
  • FIG. 12 shows a schematic view of the protective cover according to the embodiment shown in FIGS. 5 and 6 , and having a plurality of openings;
  • FIG. 13 shows a tilted enlarged schematic view of the protective cover from FIG. 12 ;
  • FIG. 14 shows a perspective view of the protective cover configured as a partial cover.
  • FIG. 1 shows a perspective view of an electrical connector 100 for contacting a circuit carrier 114 (see also FIG. 4 ).
  • the connector 100 has a plurality of contacts 102 , which are assembled in an electrically insulating housing 104 .
  • the contacts 102 have contact portions for contacting a mating contact (not shown) and connecting portions 106 for contacting a plated through hole 116 ( FIG. 4 ) of the circuit carrier 114 ( FIG. 4 ) via an electrically conductive press-in connection.
  • the connecting portions 106 or “pins” are configured such that when the connecting portions 106 are pressed into the plated through hole 116 ( FIG. 4 ) of the circuit carrier 114 ( FIG. 4 ), the connecting portions 106 may produce an electric contact.
  • the circuit carrier 114 ( FIG. 4 ) is generally a printed circuit board.
  • other highly diverse circuit carriers in which whisker formation can occur may also be equipped with the electrical connector 100 according to the invention, for example, flexible circuit carriers or ceramic circuit carriers.
  • the whiskers form on tin surfaces of a joint face between the connecting portion 106 and an inner wall of the plated through hole 116 ( FIG. 4 ) within through-holes in the circuit carrier 114 ( FIG. 4 ).
  • a mechanical screen through which the contacts 102 enter, and which rests in a planar manner on the printed circuit board, can prevent functional disturbances of electronic control apparatuses, for example, a short-circuit between the contacts 102 .
  • whiskers form especially in these regions of material accumulation under mechanical stress. If these whiskers grow out of the plated through hole 116 and reach the adjacent connecting portion 106 or if they break off and are transferred to other unfavorable locations, short-circuits and therefore serious failures may be caused. This is intolerable, in particular in conjunction with motor vehicle electronics, for example, an airbag controller, and the strict requirements occurring there with regard to long-term stability, reliability and robustness.
  • the actual physical causes of the whisker formation are not being eliminated as this is only possible by means of expensive and complex modifications to circuit carriers and/or contacts, but it is ensured that the whiskers which may possibly form cannot leave the region of the press-in connection.
  • the connector 100 therefore includes a protective cover 108 , which for each of the contacts 102 has an opening 110 , through which the connecting portion 106 enters.
  • the protective cover 108 is configured in such a way that, in cooperation with the contacts 102 and/or the electrically insulating housing 104 , the protective cover 108 covers an intake region of the plated through holes 116 ( FIG. 4 ) toward the outside.
  • the whiskers continue to be formed with a protective cover 108 , their growth is hindered by the protective cover 108 (they continue to grow in a bent form under the protective cover 108 ) and they cannot spread out of the region in or on the through-hole of the circuit carrier 114 , nor can they produce short-circuits or other failures.
  • the electrical connector 100 shown in FIG. 1 , may be kept ready with the assembled protective cover 108 and during assembly may be pressed onto the circuit carrier 114 ( FIG. 4 ), which will be explained later with reference to FIGS. 4 to 6 .
  • the openings 110 are prefabricated in the embodiment shown, but, as an alternative, may also be configured by directly pressing the protective cover 108 onto the connecting portions 106 during assembly of the electrical connector 100 .
  • the connecting portions 106 enter through the openings 110 of the protective cover 108 in such a way that an end region of the connecting portions 106 is screened relative to an outer region 118 , which is located below the protective cover 108 in FIG. 2 .
  • the protective cover 108 is formed by a flat perforated plastic material plate. A surface of the protective cover 108 , which faces upward in FIG.
  • FIG. 3 shows a detail 3 from FIG. 1 in an enlarged and partially sectional view.
  • extensions 112 of the connecting portions 106 are surrounded in a particularly flush manner by the protective cover 108 to prevent a growth of whiskers forming preferentially at this location to the outside.
  • FIGS. 4 to 6 show other embodiments of the electrical connector 100 after assembly in circuit carrier 114 . These views are turned 180° relative to those of FIGS. 1 to 3 , i.e. the connecting portions 106 are shown directed downward here.
  • the protective cover 108 closes the extensions 112 relative to an outer region 118 remote from the circuit carrier 114 .
  • FIGS. 4 to 6 Various configurations of the protective cover 108 are shown in detail in FIGS. 4 to 6 , the embodiment shown having a more complex geometric configuration than the protective cover 108 of FIGS. 1 to 3 .
  • the protective cover 108 of FIG. 4 has a step 120 , which is formed by a one-sided indentation and supports the protective cover 108 opposite the insulating housing 104 .
  • an edge of the opening 110 of the protective cover 108 surrounds the connecting portion 106 in a flush manner so the protective cover 108 in cooperation with the electrically insulating housing 104 and the connecting portion 106 covers the intake region of the plated through hole 116 , in which the extensions 112 are located, from the outer region 118 .
  • the protective function according to the invention can also be achieved in that the covering of the extensions 112 from the outer region 118 is only implemented by the cooperation between the housing 104 and the protective cover 108 .
  • This has the advantage that a secure sealing and protective function can be achieved even without having to ensure peripheral mechanical contact between the contacts 102 and the protective cover 108 .
  • this variant assumes that the connecting portions 106 are held in the plated through hole 116 so firmly that no play can occur between the protective cover 108 and the electrically insulating housing 104 .
  • FIG. 6 A combined variant, in which the protective cover 108 cooperates both with the contacts 102 and with the electrically insulating housing 104 to seal the extensions 112 from the outer region 118 , is shown in FIG. 6 .
  • the protective cover 108 according to this embodiment, has a sealing lip 122 , which is formed, for example, by a region with a reduced material thickness which directly surrounds the contact 102 .
  • the protective cover 108 for this embodiment is as far as possible formed by a resilient material, such as, for example, silicone or a thermoplastic elastomer, as the sealing function of the sealing lip 122 can be ensured most easily in this manner.
  • FIGS. 7 to 11 show various possible configurations of the protective cover 108 .
  • the protective cover 108 may consist of a flat plastic material plate or film, into which the openings 110 are introduced as perforations. This corresponds to the protective cover 108 shown in FIGS. 1 through 3 .
  • the step 120 can be implemented by a one-sided indentation, as shown in FIG. 8 .
  • Step-like edge regions of this type of the openings 110 can, depending on their size in relation to the dimensions of the plated through hole 116 and the connecting portions 106 , either be assembled as in FIG. 4 or be inserted according to FIG. 5 .
  • FIG. 9 shows an embodiment in which a supplemental layer 126 extends from a rigid carrier layer 124 forming the protective cover 108 .
  • the supplemental layer 126 may be a gel pad, foam material, or an adhesive.
  • the resilience of a supplemental layer 126 prepared from a gel pad, allows tolerances to be compensated within certain limits, so no undesired openings remain through which the whiskers could grow.
  • one or more surfaces of the protective cover 108 may be adhesively coated or consist, in individual layers, of adhesively coated strips or films.
  • a self-adhesive film, as a supplemental layer 126 may optionally also be applied in advance to the circuit carrier 114 .
  • the entire protective cover 108 may be produced from a gel or a foamed material.
  • FIG. 11 schematically shows the protective cover 108 corresponding to the embodiment of FIG. 6 , in which the sealing lip 122 is formed, for example, of a silicone material.
  • FIG. 12 shows the protective cover 108 , analogous to the variant from FIG. 8 , for a plurality of the plated through holes 116 and the connecting portions 106 corresponding to the embodiment of FIGS. 1 and 3 .
  • the protective cover 108 of this type is produced as one piece.
  • the whisker protective function can be implemented for a plurality of press-in connecting portions 106 in one working step.
  • FIG. 13 shows the view of FIG. 12 , turned and enlarged.
  • the variant in which the protective cover 108 is produced in one piece for a plurality of the contacts 102 requires a comparatively flat circuit carrier surface.
  • no differences in level should occur between upper sides of the individual plated through holes 116 .
  • a separate partial cover 128 may also be provided, as an alternative, for each of the contacts 102 or a smaller group of the contacts 102 . This scenario is shown schematically in FIG. 14 .
  • the existing so-called Sn-Flash surface can thus be used at the contacts 102 despite a technologically induced whisker formation, as the whiskers cannot have any function-impairing influence on the surroundings, because of the protective cover 108 .
  • whisker-free surfaces not based on tin, which have an unacceptable press-in and press-out behavior, do not have to be used.
  • the present invention is therefore suitable, above all, for airbag control apparatuses, which have to have a high degree of reliability and an optimal electric contact.
  • any functional disturbance at electronic control apparatuses through whisker formation in the contacts 102 on electroplated pure tin surfaces can be prevented.
  • neither the materials of the circuit carrier 114 nor the surfaces of the connecting portions 106 of the contacts 102 have to be modified, and the required guidelines for environmentally friendly product design can be adhered to, as well as the stringent requirements for reliability and security against failure of connections of this type in the motor vehicle sector.
